Abstract: A retaining wall comprising a grid-shaped framework fabricated by a plurality of groups of members joined end to end in a vertically aligned relationship and another plurality of groups of members also joined end to end in a horizontally aligned relationship. The ends of the vertically positioned members meet the adjacent ends of the horizontally positioned members at right angles thereto to define a multiplicity of cruciform patterns which combine in a mutually overlapping manner to form the retaining wall.

Abstract: Specially shaped concrete wall blocks which can be readily put together to form a retaining wall which is not easily collapsible. The block of the H-shaped construction comprises a front wall, a rear wall which is parallel to the front wall and a member connecting the front and rear walls. The front wall is of the integrally formed three-part construction. Two of the parts are diagonally offset relative to each other by an intermediate rhomboidal portion interposed therebetween. The sloping surfaces formed around the front wall by the rhomboidal portion provides means for holding together the blocks assembled into a retaining wall. According to one embodiment of the invention, the block is shaped in the form of a regular H while it is in the form of an inclined H according to another embodiment.
